摘要
研究黄沙坪铅锌矿床中银矿化组合表明:与301花岗斑岩和304花斑岩岩体有关铅(锌)-银-锡-锑矿化组合,银矿化伴随铅矿化出现,其微量元素富Sn、Sb、Ag,低Bi、Te、Mo、Wo、W为特征;银矿物组合以硫银锡矿-银黄锡矿-深红银矿-螺状硫银矿-硫锑铜银矿组合为特征,与石英斑岩有关的铜(钼)-银-碲矿化组合,铜矿石以高Te、Bi、Mo和W,低Sb为特征。
Two different kinds of minernlization associations of silver polymetals can be classified in the Huangshaping lead zinc deposit.One is the Pb(Zn) Ag Sn Sb mineralization association which is related to the graniticporphyry 301 and granophyre 304.Silver mineralization is accompanied by lead,and charaterized by high contents of Sn,Sb,Ag and low content of Bi,Te,Mo,W.Its mineral association is featured by canfieldite hocartite pyrargyrite acanthite polybasite.The another one is the Cu(Mo) Ag Te mineralization association related to quartz porphyry.The copper ores are rich in Te,Bi,Mo,W,and low in Sb.The mineral associations are characterized by hessite stuetzite empressite,and matildite schirmerite hessite association.
